  • Method for manufacturing extraction bag sheet
    Patent number: 8500617
    Abstract: A method of manufacturing an extraction bag sheet including: (1) a step of placing and holding tags on a rotary supporting body at predetermined intervals; (2) threading a string into a continuous pattern on the circumferential surface of the rotary supporting body; (3) bonding the string to the tags; (4) supplying a water-permeable filter sheet onto the tags and the string; (5) bonding the water-permeable filter sheet to the string; and (6) bonding the water-permeable filter sheet to the tags. In the bonding steps of (3), (5), and (6), bonding heads are used which are moved reciprocally and oscillatingly about the center axis of the rotary supporting body and moved vertically relative to the circumferential surface of the rotary supporting body by an oscillation servo motor and a vertical movement servo motor.
